Israel action against Bedouin tribesmen, whose alleged expulsion from the El Auja area into Egyptian territory is the subject of a complaint by Egypt now pending before the U.N. Security Council, was supported here today by the findings of the Egyptian-Israeli Mixed Armistice Commission.

The commission, meeting yesterday at El Auja under the chairmanship of Col. P. Boissavy, French member of the U.N. truce mission, placed on record the fact that the expelled Bedouins were members of the Azazmeh tribe and had infiltrated into Israel territory from Sinai, which is Egyptian. Supporting evidence was collected from the Bedouins themselves by U.N. observers.

Col. Boissavy ratified these findings as well as Israeli claims that the tribesmen were not in Israel when the Egyptian-Israel armistice was concluded and that the tribesmen did not possess the Israel identification cards issued then to all tribesmen residing on Israel territory. The U.N. observers also established the fact that the seat of the Azazmeh tribe was in Kussima, in the Egyptian part of the Sinai peninsula, where the tribesmen regularly bought their supplies.
